Value Collection 833180PR M12 Dog Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 833180PR is a dog point set screw designed for mechanical assemblies where positive shaft location and resistance to loosening are required. Threaded M12 x 1.75 with an overall length of 40 mm, it is manufactured from alloy steel to Grade 14.9 (45H), delivering high tensile and torsional strength suitable for demanding industrial and mechanical applications. The black oxide finish provides a base level of corrosion resistance and reduces light reflection. Installation requires a 6 mm hex key. This fastener is produced to DIN 915 and ISO 4028 standards, making it a dimensionally consistent choice for precision assemblies.

This set screw is used in applications where a protruding dog point is needed to locate into a mating hole or groove on a shaft, preventing axial movement without the need for a separate dowel or pin. Typical installations include motor shafts, gearboxes, collars, couplings, and rotating assemblies in industrial machinery. Machinists, millwrights, and mechanical assembly technicians install this type of fastener in both OEM manufacturing and maintenance-repair-overhaul environments. The metric M12 x 1.75 thread pitch suits equipment built to metric standards.

Key Features

• Dog point tip provides positive shaft location by seating into a drilled receiving hole or groove
• Grade 14.9 (45H) alloy steel construction delivers high clamp load and shear resistance
• Black oxide finish reduces surface corrosion and minimizes galling during installation
• Manufactured to DIN 915 and ISO 4028 standards for dimensional consistency
• 6 mm internal hex drive for precise torque application with standard hex keys or T-handle drivers
• Metric thread M12 x 1.75 for compatibility with metric-standard mechanical assemblies

Compatibility

Designed as a DIN 915 and ISO 4028 compliant M12 x 1.75 dog point set screw suitable for metric-threaded collars, couplings, hubs, and shaft assemblies requiring a dog point engagement feature.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 6 mm hex key or driver. Ensure the mating shaft or component has a properly sized receiving hole or groove machined to accept the dog point before tightening. De-energize and lock out any rotating or powered equipment before servicing shaft-mounted components. Do not exceed the torque capacity of the fastener grade; consult applicable mechanical engineering references for M12 Grade 14.9 torque specifications relevant to your assembly.
